I am also in same boat. I medical in done on Mar 16, no news yet. I also do NOT see medical received at ecas. But I checked in Fedex tracking they were received in march itself. I sent RPRF check with DMP Receipts, which has been en-cashed long back. But so far I am waiting.
canada0801 also in same boat.
I would advise that we wait for some more time... The medical document which I received had a line that we if comply to document/medical request, we should wait for 90 days before making any inquiry.
